ABO blood group system - Wikipedia
The ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes (red blood cells). [1] For human blood transfusions , it is the most important of the 44 different blood type (or group) classification systems currently recognized by the International Society of Blood Transfusions (ISBT ...

Although the ABO blood group antigens are regarded as RBC antigens, they are actually expressed on a wide variety of human tissues and are present on most epithelial and endothelial cells. Each human RBC expresses about 2 million ABO blood group antigens.

Sep 9, 2023 · ABO Antigens and Antibodies. People can be divided into four main groups (A, B, O, and AB) based on the agglutination patterns of their red blood cells. The ABO blood group system consists of A and B antigens on red blood cells and their corresponding antibodies in the sera of people who do not express those antigens.
ABO blood group system | Definition, Blood Type, & ABO Antigens ...
Nov 28, 2024 · ABO blood group system, the classification of human blood based on the inherited properties of red blood cells (erythrocytes) as determined by the presence or absence of the antigens A and B, which are carried on the surface of the red cells. Persons may thus have type A, type B, type O, or type AB blood.
ABO Blood Group System: Antigens, Typing and Tests
ABO blood group is the most important blood group system in transfusion and organ transplantation medicine. ABO antigens can be found on red cells, white cells, platelets and many circulating proteins. Transfusion incompatibility can cause acute intravascular hemolysis, renal failure and death.
Blood group antigens are surface markers on the red blood cell …
The antigens expressed on the red blood cell determine an individual's blood group. The main two blood groups are called ABO (with blood types A, B, AB, and O) and Rh (with Rh D-positive or Rh D-negative blood types). The functions of many of the blood group antigens are not known, and if they are missing from the red blood cell membrane, there ...
Human ABO Blood Groups and Their Associations with Different …
Human ABO blood type antigens exhibit alternative phenotypes and genetically derived glycoconjugate structures that are located on the red cell surface which play an active role in the cells' physiology and pathology.
ABO Blood Group - PubMed
There are four common blood groups in the ABO system: O, A, B, and AB. The blood groups are defined by the presence of specific carbohydrate sugars on the surface of red blood cells, N-acetylgalactosamine for the A antigen, and D-galactose for the B antigen.
ABO blood group antigens and differential glycan expression ...
Jan 20, 2023 · The ABO blood group system contains the A, A 1, B, and A,B antigens, whereas the H blood group system contains the H antigen, which is the precursor for the others (ISBT, 2021). A and B structures are added to type 1 and 2 H chains. Blood group O individuals cannot synthesize A or B antigens, and so they only express the H antigen.
Beyond immunohaematology: the role of the ABO blood group …
It has long been known that the ABO blood type has a profound influence on haemostasis, being a major determinant of the von Willebrand factor (VWF) and, consequently, of factor VIII (FVIII) plasma levels 5–7. In detail, VWF levels are approximately 25% higher in individuals who have a blood group other than O 8.
